I use the Focal CMS 65 and I can onestly say that they sound fantastic. Even if I have some resonance issue in my room, this monitor are incredible for mixing, it's absolutely true that they give you the possibilities to hear everything and understand easily what to you want and what you don't want to hear!
Let's say that bad mix or bad sound are shown exactly how they are, so they don't hide nothing...
For the KPA it's the same, you can easily tweak your sound to use after in any pa system without bad surprises. But if are hearing a bad sound for your guitar that's shown in front of you directly!
I believe in general that for the kpa 8 inch woofer is still better... this monitor have 6,5 inch, and anyway the bass response is still full, rich and harmonic, plus the monitor are the smaller I found with such great performance. If you don't have problem of space think about an 8 inch monitor but be careful that the sound remains still linear and that the bass response doesn't cover meedle freq spectrum!
For the nearfield stuff, you can use it without problems until 2-3 meter of distance and appreciate all the clarity and power.
So, let us know your final decision
